You can throw your computer out of a 10-story window - but just because you can do it doesn't mean it's a good idea. It's just wrong. In your particular case it depends on whichever library/ interface/ application you're using to communicate with PG (e.g. PGSQL manager, the dump and restore tools, PHP's library, libpq.dll etc) - as they will all have to realise that there is a dot in the table/column name, and will have to quote it, or PG will complain. And you'll have to remember to quote it too when manually writing queries - it's just extra work that's plain unnecessary. Plus if/when you encounter problems in the future, the first thing that people are going to see is the dot in the table/column names and question if that's what is causing the problem, as in problem-solving you always look for the obvious first. Why are you so insistent you want to use a dot? Can't you use underscores instead?
